Fear is a killer: Nuclear expert reveals radiation’s real danger – energy


Experience in Nagasaki, Chernobyl and Fukushima has taught Shunichi Yamashita that anxiety and disruption can hurt people far worse than radiation itself.

“Many people thought even a tiny amount of radiation was dangerous”

Mass screening done anywhere is bound to show up cancers that wouldn’t otherwise have been diagnosed. They have nothing to do with radiation, but the public and the media don’t understand this.

    It goes completely against what most believe, but out of all major energy sources, nuclear is the safest

    One terrawatt-hour is roughly equivalent to the annual energy consumption of 12,400 US citizens. Although deaths from accidents and air pollution have been combined, it’s important to note that air-pollution related deaths are dominant. In the case of brown coal, coal, oil and gas, they account for greater than 99% of deaths, as well as 70% of nuclear-related deaths4, and all biomass-related deaths.

    We can see that brown coal and coal rate the worst when it comes to energy-related fatalities. Coal-fired power plants are a key source of sulphur dioxide and nitrogen oxides, key precursors to ozone and particulate matter (PM) pollution, which can have an impact on human health, even at low concentrations.

    Russia Detects a Significant Radiation Spike In Mountains Close To Soviet-Era Nuclear Plant

    According to a report via The New York Times, Russia said that it had detected a significant radiation spike in the Ural Mountains, close to a sprawling Soviet-era nuclear plant still remembered as the site of an accident 60 years ago. Russia did however reject suggestions that it was the source of a radioactive cloud that hovered over Europe.

    The location of the spike — in the Chelyabinsk region near the border with Kazakhstan — has been identified by French and German nuclear safety institutions as a potential source for a concentration of a radioactive isotope called ruthenium 106 detected in the air in late September above several European countries. But nuclear energy authorities in Moscow insisted Monday that still-higher levels of atmospheric contamination had been detected outside Russia, in southeastern Europe.

    Russian radiation leak: everything you need to know

    ‘Extremely high’ levels of a radioactive isotope were discovered in parts of Russia in September. But where did it come from? And is it dangerous?

    Is it dangerous?

    The highest levels reported were 986 times the background levels, which sounds alarming. However, the background levels are close to zero and nuclear safety experts believe the leak is unlikely to pose a health risk or require people in the vicinity to be evacuated. Professor Paddy Regan, a nuclear expert at the University of Surrey told me: “The levels detected may be extremely high relatively to the background, but they’re not extremely dangerous.”
    How long will it stick around for?

    The half-life of Ru-106 is 374 days, meaning that in just over a year, half of the material will have decayed away. So the leak will still be detectable for five or six years, but it is unlikely to require any major environmental cleanup operation.

    Homes should not be abandoned after a big nuclear accident

    New research suggests that few people, if any, should be asked to leave their homes after a big nuclear accident, which is what happened in March 2011 following the Fukushima Daiichi nuclear disaster.

    This is the main finding of a multi-university research study led by Philip Thomas, Professor of Risk Management at the University of Bristol, involving the universities of Manchester and Warwick, The Open University and City, University of London. The results are published in a special issue of Process Safety and Environmental Protection, a journal from the Institution of Chemical Engineers.

    “Mass relocation is expensive and disruptive. But it is in danger of becoming established as the prime policy choice after a big nuclear accident. It should not be. Remediation should be the watchword for the decision maker, not relocation.”

    It Sounds Crazy, But Fukushima, Chernobyl, And Three Mile Island Show Why Nuclear Is Inherently Safe

    Radiation from Chernobyl will kill, at most, 200 people, while the radiation from Fukushima and Three Mile Island will kill zero people.

    In other words, the main lesson that should be drawn from the worst nuclear accidents is that nuclear energy has always been inherently safe.

    “What About Chernobyl?” Ranking World’s Deadliest Energy Accidents

    When nuclear power comes up, more often than not someone declares that all anyone needs to know can be said with one word: Chernobyl.

    But the big picture is vague, grey, and complex. The name of that place — Chernobyl — and the accident it’s irrevocably linked with, burns with a bright red focus in people’s minds. Chernobyl disaster might be the most famous accident in the world.

    What about workers and their families who were killed and whose homes were destroyed by gas explosions or coal mine fires, or the tens of thousands who have drowned after dam breakages? And what about the millions who die every year, in the non-accident that is the steady production of particulate air pollution?

    Chernobyl in context
    Chernobyl accident directly cost 31 lives, and caused some 106 injuries among the cleanup-workers and firemen. Further injuries include thousands of cases of thyroid cancer.

    Most of the cases are easily treatable and fatalities are expected to stay low — so far, 15 deaths from thyroid cancer have been connected to exposure from the accident. This figure may eventually reach 160

    If we compare direct death tolls of the largest energy accidents (graph), we quickly notice that there is one accident above others: the massive flood after the dam failure in Banqiao, China, in 1975.

    What If You Fell Into a Spent Nuclear Fuel Pool?

    Spent nuclear fuel pools are designed to cool fuel rods after they come out of a nuclear reactor. While powering a nuclear reactor, these fuel rods become very, very hot (2,800 degrees Celsius / 5,092 degrees Fahrenheit). After they spent 3 to 6 years inside of a nuclear reactor, fuel rods are no longer efficient. Problem is, they still emit plenty of harmful radiation, and they will for the next 10,000 years.

    Accident Tolerant Fuel Cladding: Extreme Material Demands in Nuclear Reactors

    The release of radioactivity to the environment is a major threat to people’s health in the case of a nuclear accident. The most critical barrier to the release of radioactivity to the environment is the fuel cladding.

    The conventional Zircaloys discovered in the 1950s, with some modifications, are still being used as cladding materials in current reactors. Efforts are underway to find and test the alternative fuel cladding materials better than Zircaloy,

    Rocket Explodes During Test, Killing Two People

    A rocket exploded on August 8 in the Russian military range of Nyonoksa, injuring four people and killing two. Russian’s defense ministry reported that the explosion caused a fire, but that no radioactive or toxic material was released.

    However, this doesn’t seem to match with what was measured in the city of Severodvinsk, 30 kilometers (19 miles) east of the naval base of Nyonoksa.

    Building nuclear weapons is easy. Cleaning up the radioactive waste is very, very hard.

    A Glass Nightmare: Cleaning Up the Cold War’s Nuclear Legacy at Hanford

    At the Hanford Site in south-central Washington state, 177 giant tanks sit below the sandy soil, brimming with the radioactive remnants of 44 years of nuclear-materials production. From World War II through the Cold War, Hanford churned out plutonium for more than 60,000 nuclear weapons, including the atomic bomb that razed Nagasaki, Japan, in August 1945. The sprawling enterprise eventually contaminated the soil and groundwater and left behind 212 million liters of toxic waste

    Fukushima radiation hasn’t killed anyone, but evacuation has.

    Fukushima radiation did not damage health of local people, UN says

    ‘No adverse health effects’ detected despite three nuclear reactors being destroyed by an earthquake and tsunami in 2011

    Radiation caused by the nuclear meltdown in Fukushima a decade ago has not damaged the health of local people, according to a UN report.

    Gillian Hirth, chairwoman of the UN’s scientific committee on the effects of atomic radiation (Unscear), said that “no adverse health effects among Fukushima residents have been documented that could be directly attributed to radiation exposure from the accident” in March 2011.

    Aika hassua. Minä käsitin, että Vihreiden, Greenpeacen ja muiden alan toimijoiden mukaan ydinvoima oli ja on faktapohjaisesti ja todistetusti erittäin vaarallista, kallista, vanhanaikaista ja myös tarpeetonta. Jos näin todella olisi, silloin ydinvoimalle ei saisi antaa piiruakaan periksi vaan se pitäisi ehdottomasti kieltää kansainvälisin sopimuksin. Miten tuosta tilanteesta ja näkemyksestä on voitu päästä tilanteeseen, jossa se onkin jollain tavalla hyväksyttävää tai ei-tuomittavaa. Ovatko faktat muuttuneet?

    Ympäristöjärjestöjen ydinvoimavastustus on hiljentynyt – “Ydinvoimalat ovat osa Suomen energiapalettia, pitipä siitä tai ei”

    Laitosten konfliktialttius huolettaa järjestöjä.

    Ydinvoimaan kriittisesti suhtautuneet Suomen keskeiset ympäristöjärjestöt eivät koe asiaa enää uhkaavaksi, vaan osana ilmasto- ja energiakriisin ratkaisua. Greenpeace ja Suomen luonnonsuojeluliitto odottavat tuulivoimasta kuitenkin ydinvoimaa suurempaa ratkaisijaa.

    Ilmastokriisi ja Venäjän käymä energiasota Eurooppaa vastaan vaativat tehokkaita ja vähäpäästöisiä ratkaisuja energian tuottamiseksi. Ympäristöjärjestöjen kritiikin kohteena olleen ydinvoiman, ja erityisesti Olkiluoto 3 -ydinvoimalan, odotetaan helpottavan Suomen talven energiapulaa.

    “Kiista ei ole ajankohtainen”

    Ydinvoimaa vastustanut ympäristöjärjestö Greenpeace ei koe asiaa ajankohtaisena ongelmana Suomessa. Suurimpina huomion aiheina järjestössä nostetaan ilmastokriisin ratkaiseminen, päästöttömän energian lisääminen ja luonnon monimuotoisuuden kriisi.

    Greenpeacen uutena Suomen maajohtajana tänään aloittava Touko Sipiläinen kertoo suhtautuvansa ydinvoimaan käytännönläheisesti.

    – Kiista ydinvoimasta ei ole tällä hetkellä ajankohtainen energiapolitiikan ja ilmaston näkökulmasta, Sipiläinen sanoo.

    Ydinvoimalat koetaan Suomen Greenpeacella edelleen hitaaksi ja kalliiksi rakentaa. Olkiluodon ydinvoimalan viivästymiset ja nousseet kustannukset ovat osaltaan vaikuttaneet mielikuvan syntyyn.

    Sipiläisen mukaan heidän odotuksensa ovat voimakkaasti kasvavan tuulivoiman määrässä. Suomen kantaverkosta vastaava Fingrid vahvistaa tiedon, että tuulivoiman tuotantokapasiteetin odotetaan Suomessa ylittävän ydinvoiman vuoteen 2027 mennessä.

    – Päästövähennyksiä täytyy saada mahdollisimman nopeasti, jotta vältytään katastrofaaliselta lämpenemiseltä, Sipiläinen sanoo.

    Vaikka järjestöt ovat edelleen tuulivoiman kaltaisten uusiutuvien energiamuotojen kannalla, koetaan ydinvoima välttämättömäksi energiamuodoksi ympäristökriisin ratkaisussa.

    – Ydinvoimalat ovat olemassa oleva realiteetti. Ne ovat osa Suomen energiapalettia, pitipä siitä tai ei, Suomen luonnonsuojeluliiton toiminnanjohtaja Tapani Veistola sanoo.

    Japan lacks the expertise for renewed nuclear power after Fukushima https://www.theregister.com/2023/01/04/japan_nuclear_expertise/
    Japan’s decision to reignite its nuclear power industry is facing serious setbacks: 11 years of prohibition has led to a shortage of engineers, a lack of students training to fill vacant positions and a dearth of domestic nuclear manufacturing capability. The Japan Electrical Manufacturers’ Association claims the number of “skilled engineers responsible for manufacturing nuclear equipment” has declined by 45 percent since the government banned nuclear power projects and shut existing reactors in response to the Fukushima meltdown in 2011.

    The Soviet Union’s Deadly Abandoned Nuclear Generators

    Radioisotope Thermoelectric Generators, or RTGs (sometimes incorrectly called Nuclear Batteries) are usually utilized in deep space exploration.
    But during the 1970s and 1980s, during the height of The Cold War, The Soviet Union manufactured over 2500 terrestrial RTGs to power its unmanned Lighthouses and Radio Navigation Beacons on the Northern Arctic seaboard, or deployed in the USSR’s remotest hinterland rural regions.

    When the Soviet Union collapsed in 1991, all these highly dangerous, intensely radioactive devices were simply abandoned in situ, and left to rot for the next 2 decades…. until they started to kill people in the 21st century, with Acute Radiation Exposure. This finally caused the international community to start to take the hazard they posed seriously.

    This 30 min video is a documentary on the reasons the Soviet Engineers chose to use dangerous Radioisotope Thermal Generators to power equipment, the technology and nuclear physics behind them, with the help of Matt Damon in the movie ‘ The Martian’ (2015) .
    We explore some Abandoned Places in the Former Soviet Union that are still home to decaying RTGS , such as Aniva Lighthouse, on Russia’s Sakhalin Island.
